Abstract
Passenger comfort has become an important requirement for manufactures to achieve because of the direct effect on its seals rate the driver has been concentrate on this study to decrease the vibration that reach on him that cause unclear of his vision when driving and to achieve this goal a tow – dimensional model has been chosen to represent suspension system of halve truck vehicle for fore degree of freedom (4DOF) and by add one degree of driver seat .
In this study and to obtain accurate result we study the Non – Linear factors that act on the suspension system performance Taking into account one of the most important sources of nonlinearity, which is the non-linear behavior of the damper and the second source is the extended contact of the tire .
By considering the body of the vehicle is rigid The equations of the movement were derived using Newton's second law and excitement the car by using two types of obstacles , the first is halve sine wave and the second is trapezoidal as an expression of the road irregularity that the car is exposed through traveling and to obtain the results a Fortran 90 computer program was created for the purpose of solving mathematical equations. After running the program we obtain the results represented by displacement , velocity and the normal acceleration in the center of gravity of cars body .
The results were compared with the results of newly published research adopted The nonlinear behavior of the suspension systems and it was found that is approaches by acceptable degree and to find out the extent of improvement in the results when considering the nonlinear factors we compare with the linear symbol of same vehicle and by use same excitation It was found that the adoption of nonlinear factors leads to improved results .
Then we carried out to ride comfort To know what results we have achieved when adopting the nonlinear factors Through the adoption comfort criteria the first was the amount of maximum acceleration of the driver's seat and the second is the amount of Absorbed Power then its found that depending the Non – Linear factors give more flexibility to determining the ride seat connect with respect to center of gravity of car body with determination the optimum place to connect it that leads to obtain minimum percentage of vibration .
